Hello Maldon, I managed to get everything working on the DELL Latitude 7390. However, I have a problem with the temperature which exceeds 90 degrees even with the fan on full blast. The EFI that I transformed I think is are you the one who created the SSDT, for a 7490. If you need my EFI, tell me how I can post it on your site so I can share it too

[MaLd0n]

U can share for us  

90 on mobile is common on full

iddle 35/45

Tu peux partager pour nous 

90 sur mobile est courant sur plein

ralenti 35/45

The minimum/maxi temperature at idle is between 65/75 degrees

Attached is the link for sharing my Somona EFI with Broadcom Wifi/Bluetooth card
Don't forget to create your SMBIOS in 15.2
OpenCore:0.9.7https://mega.nz/file/6csTWZgZ#lgFgslZWqwbg0J93HZ7rm4h01iSPGv2SOZC3Tv4xU7g

Generate CpuFriend

Thank you for your answer but with CpuFriend it didn't change anything

[jojodu13230]

Good evening Maldon, can you give me a DSDT to lower the CPU temperature? Thanks in advance

[MaLd0n]

is not about dsdt

[jojodu13230]

can you help me. find the solution if it pleases you?

you need to update the driver for Intel Dynamic Tuning Driver

hey jojodu13230
I have installed macOS so many times but failed
but this time, I used the EFI that you provided & now I am able to install it successfully
Thanks for that. I really appreciate that!

just having an issue 
wifi and Bluetooth are not working. Unfortunately, I have a 7390 2-in-1 model, so I do not have any ethernet port. So it would be useless for me without wifi
Could you please guide me on how to make them work?

I would really appreciate the effort
Thanks in advance.
